The music in the Season 7 episodes are redubbed with music from the New Series.

This is the only time that the title cards were presented at the beginning of the Classic Series Episodes in the UK.

At the end of Thomas, Percy & the Squeak, the squeaking noise is different.

In "What's the Matter with Henry?" Thomas has an extra puffing sound going past the lighthouse at the beginning. Gordon also has an extra puffing sound when going down his hill at the beginning of "Gordon and Spencer".
